XCube: Large-Scale 3D Generative Modeling using Sparse Voxel Hierarchies

Xuanchi Ren, Jiahui Huang, Xiaohui Zeng +3

We present XCube (abbreviated as ${\mathcal{X}}^3$), a novel generative model for high-resolution sparse 3D voxel grids with arbitrary attributes. Our model can generate millions of…
